Здравствуйте.
Есть так проблема с Zyxel USG 60
Была настроено предыдущим админом L2TP подключение из вне.

Всё работало нормально до определённого момента, двум разным компьютерам (мой офисный с другой работы и бухгалтера) не удаётся подключиться , выдаёт ошибку (во вложении) 
Причём с других 3-ёх компов подключается без проблем.
Настройки никакие не менял. В чём проблема - не пойму.

Подскажите пожалуйста.


Вот лог
